The title of this thread is that 780g chipset is bad for Mediaportal. Is that still valid? Sorry but reading the whole thread and getting the aswer if every issue found is solved or not is really hard.

So, is it good?

I think a lot of the bad press was to do with the Gigabyte MA78GM-S2H board which seems to have been released a little too quickly so wasn't tested properly and the drivers have constantly had to fix issues with it- see this thread at avs forums. The fact the board has had two hardware revisions, 1.1 and now 2.0 from the original release suggest that this is the case. It does seem a lot of problems have been fixed with driver updates but there are also quite a few eccentricities and workarounds that can be useful to know that I will be listing on the thread in the next few days.

    @ErikLarsson Mine works great, recommended.

    Hi,

    which OS/Codecs do you use? I havent found a solution to play all videos (some mkv's dont work at all, others with errors or perfectly fine). Everytime I change something, one video suddenly plays great and another one not.

    I wonder if a Phenom-CPU (currently BE2400) might help, but I doubt it.

    MPC-HC (Media Player Classic - Home Cinema) works fine for me as an external player on XP SP3 and Catalyst 8.10. It gives hardware acceleration (DXVA) on all my HD h.264 and VC-1 files. Download the standalone player here for x86 (32 bit) OS, and here for x 64 (64 bit) OS - the latest builds 845 and 849 both work well. Unfortunately the MPC video decoder doesn't currently work for HDTV so I still have to use Cyberlink/Arcsoft for that. If you don't need HDTV or ability to read .ts files you can install Hoborg's SAF pack here.

    +1 MPC-HC standalone does well for h264 in XP/780G

    NB: you mentioned it doesn't work with some mkv files, that maybe because they are not encoding correctly. There are some files with bad encoding that will never hardware accelerate im told.

    For the majority out there around the world, yes. For me with NZ's DVB-T Freeview (not DVB-S), no. I can get DXVA working for most channels but some (576i) I cannot - screen is blocky green. I've tried nearly all Catalysts up to 8.10 under XP 32-bit and Vista 64-bit with PowerDVD 7.3 and 8. I survive with CoreAVC, but some channels (1080i) are noticably jerky.

    If I could force MP to use a different codec for the 576i, then I would be a happy man. At the moment, I'm checking out prices on NVidia cards having wasted a weekend on Vista installs.

    Are you sure this is a h.264 problem? In AUS, all the DVB-T FTA channels (including HD) are broadcast using MPEG-2. I thought the HD channels would have been h.264, but they are not. I think only a few European channels, like BBC HD are actually using h.264 atm.

    I'm using a G35 chipset, per my specs, and have been interested in this thread because I've heard good things about the 780G. I use CoreAVC for h.264, and other than 30% CPU utilisation, don't have any problems playing 720p / 1080p movies. My main problem is with HD TV using MPEG-2 (PDVD8), where the motion looks like it has a bit of "Telecine judder", but TV server is telling me the signal is progressive, so it can't be de-interlacing that's the problem.

    Interestingly, the only solution that seems to do "full" HA of MPEG-2 is the G45 chipset or the ATI 4550 or higher, according to this site:

    Missing Remote

    Maybe I'll wait to see if they build a chipset based on the 4550 or better.

    The Nvidia's seem to be behind ATI and Intel when it comes to HA at the moment.

    I thought of that, too. But they work just fine in WMP, DVBViewer and MPC HC or in Media Portal on my Notebook. The strange thing is: if I set decoder options to automatically (warning direct show merits...) most videos play fine. Then I look which codecs are used with Graphedit and set them manually. But guess what - its not working anymore. I could live with the automatic settings - but with them no mpeg2 is working anymore. You fix one thing, the other goes to waste. Maybe I give the Mobo+CPU to my father and buy a new model...

    Did you try using Haali media splitter instead of the internal MPC-HC splitter?

    576i would be covered by the MPEG codec wouldn't it? Are your HD channels also mpeg? What decoders have you tried?
